Figure 3-15. Transmitter Overhead (OVHD button) (SDH)
The Transmitter overhead byte menus can be used to pass or change the 2.4 Gb/s signal overhead
bytes, in the first column of the STM-1. The Transmitter OVHD (overhead) button, on the lower
left side of the ST2400A front panel, is used to scroll through the Regenerator Section (RS) and
Multiplexer Section (MS) overhead bytes. The top line of each display identifies the designated
SDH overhead byte. The bottom line is used to either PASS or SET (change) the value. When the
cursor is on PASS, the byte is hidden. When the cursor is moved to SET the byte value is
displayed and the Enter key LED starts to flash. Use the arrow keys to move the cursor, and the
INC and DEC keys to change values. Pressing the Enter key or the overhead key will store the
value. The value of the editable M1 byte can range from 00 to FF.
